Consumer Surplus

kun-SOO-mer SUR-plus /kənˈsuːmər ˈsɜːrpləs/

nounC1GREGMATUPSC

FormalTechnical

The difference between the maximum price a consumer is willing to pay for a good or service and the actual price they pay.

Consumer surplus represents the economic benefit or 'extra value' consumers receive. It's a measure of consumer welfare and is graphically represented by the area below the demand curve and above the market price.

The story behind the word. This term combines 'consumer' (from Latin consumere, 'to use up, devour') and 'surplus' (from Late Latin superplus, meaning 'that which remains over and above'). The 'surplus' here isn't leftover goods, but the 'extra' value or benefit that the consumer experiences. It's the 'above and beyond' satisfaction they get because they paid less than their maximum willingness to pay.
